Other Specs
Approximate Weight per 1000:
(m) Material Thickness:0.075in.
(N) Ring Number of Turns:1.000
(Pg) Theoretical Thrust Load Capacity - Groove Yield:
Notes: Yield Strength of Groove Material (Ys): 45,000 psi. Calculated using a safety factor (K) of 2

Equation:
Pg = [ B * d * Ys * pi ] / K
    = [ (8.500 in.) * (0.106 in.) * (45,000 psi) * 3.14 ] / 2		63,655lbs.
(Pr) Theoretical Thrust Load Capacity - Ring Shear:
Notes: Ring Material: Carbon Spring Steel (SAE 1070-1090). Shear Strength of Ring Material (Ss): 120,000 psi. Calculated using a safety factor (K) of 3

Equation:
Pr = [ B * t * Ss * pi ] / K
    = [ (8.500 in.) * (0.076 in.) * (120,000 psi) * 3.14 ] / 3		81,137lbs.
